ow pulse from sensor and calculating data. The measuring CPU exchanges and controls data or information through the pro fuel dispenser cess circuit of communication signal and center-control computer. EEPROM: generally, fuel dispenser adopts model 24C16 of EEPROM, which is used for memorizing calculated information, unit price, oil density, etc. The IC chip matched with measuring CPU mainly has the memory chip of calculating data, like HX1215 and 24C16. 2.2 Keyboard At present, there are two types of keyboard used on fuel dispenser, parallel scan keyboard and serial scan keyboard. Different manufacturers employ various model keyboards with these logical units that illustrated in Diagram 3-2, 3-3 and 3-4 in their fuel dispensers. Diagram 3-2: Keyboard sketch map of fuel dispenser Diagram 3-3: Structural sketch map of parallel keyboard Diagram 3-4: Structure sketch map of serial keyboard Liquid crystal displays are adopted in keyboard screen and main display screen on which showing unit price, volume and sales. The components installed on keyboard varied largely, some manufacturers adopting touch switch, others membrane key or rubber keyboard. Parallel keyboard, high speed with many lines, is restricted by data signal length due to interference. However, serial keyboar fuel dispenser d with high anti-jamming and few lines is much freer from the length of data line. Both serial keyboard and parallel keyboard are feasible plans. 2.3 Main display screen Liquid crystal display (LCD) is generally adopted as main display board of fuel dispenser recently because it is clean and beautiful in sunlight. In order to be visible at night, transparent or semi-transparent liquid crystal screen is adopted against matrix backlight board with light-emitting diode, which also have hearting function. Display usually adopts 6-6-4 type illustrated in Diagram 3-5, showing 6 digits on volume and money, 4 digits on unit price, each item data has two digits after decimal point.

up the shortcomings of the Fourth Republic in France, hastened the arrival of the Fifth Republic under Charles de Gaull fuel dispenser e. It made unambiguous, even to the most nostalgic blimps, America s supremacy over its Western allies. It thereby strengthened the resolve of many Europeans to create what is now the European Union. It promoted pan-Arab nationalism and completed the transformation of the Israeli-Palestinian dispute into an Israeli-Arab one. And it provided a distraction that encouraged the Soviet Union to put down an uprising in Hungary in the same year. It also divided families and friends, at least in Britain and France, with a degree of bitterness that would not be seen in a foreign-policy dispute until the invasion of Iraq in 2003. If that is difficult to understand, remember that the world was a different place then. Many European politicians still believed their countries had a right to run the affairs of others. Many were also scarred by memories of appeasement in the 1930s. Faced with a provocation, even an entirely legal one involving the nationalisation of a foreign- owned asset like the Suez canal, the instinct of such Europeans was to go to war. They and their Israeli partners-in-invasion were restrained, eventually, by the United States, l fuel dispenser ed by a Republican president and war hero, Dwight Eisenhower. The venture involved intrigue, lies, nemesis—and no end of a lesson. How did it come about? The road to collusion In Egypt, the British had become so resented for their racist, arrogant ways that by the early 1950s even Winston Churchill, the grand old imperialist who had returned as prime minister in 1951, felt he could resist the tide of nationalism no more. After 1951 the British were confined to the Suez canal zone, harassed by Egyptian irregulars who wanted them out altogether. By June 1956 the last British soldiers had left even the canal zone. Yet Anglo-Egyptian relations did not improve. Nasser was enraged by America s withdrawal of its offer of loans to help fuel dispenser
